feat: add monerod detection as an option to the merge mining proxy

[hansieodendaal]

Description

• Fixed an error where the monerod server connection attempt would not timeout if it did not succeed.
• Added dynamic and robust monerod detection to the merge mining proxy as an optional alternative to the monerod URLs specified in the config. If enabled, dynamically detected monerod servers will be ordered according to the best response times.

Motivation and Context

Merge mining with monero mining recently had issues (stopped) due to a configured public monerod server not stopped being responsive anymore.

How Has This Been Tested?

• Added new unit tests for dynamic monerod detection
• Performed system-level testing

Example unit test output:

0: MonerodEntry { address_type: "clear", url: "http://213.227.135.106:18081", height: 3119866, up: true, web_compatible: false, network: "mainnet", last_checked: "5 hours ago", up_history: [true, true, true, true, true, true], response_time: Some(429.0735ms) }
1: MonerodEntry { address_type: "clear", url: "http://hatchi-home.ddns.net:18089", height: 3119865, up: true, web_compatible: false, network: "mainnet", last_checked: "5 hours ago", up_history: [true, true, true, true, true, true], response_time: Some(492.1296ms) }

4: MonerodEntry { address_type: "clear", url: "http://23.137.254.9:18081", height: 3119866, up: true, web_compatible: false, network: "mainnet", last_checked: "5 hours ago", up_history: [true, true, true, true, true, true], response_time: Some(704.3092ms) }

This reintroduces ahash, which was removed in #6238. However, it looks like the included version should be fine. Commenting here in case of future issues.
